今天遇到一个一个问题，是将字符串类型的时间转化为UTC时间。例如time_str = "2009/11/09 12:23:23" 转化为UTC int型。

找了一些资料，发现time模块就能完成这个转换。

import time time_str = "2009/11/09 12:23:23" time_s = time.strptime(time_str,"%Y/%m/%d %H:%M:%S") utc_f = time.mktime(time_s) utc_i = int(time.mktime(time_s)) print time_s (2009, 11, 9, 12, 23, 23, 0, 313, -1) print utc_f 1257740603.0 print utc_t 1257740603

在linux中输入“date +%s” 就能输出当前utc时间。
